I was on the shot for a little over two years. I started feeling sick all the time when I was on the shot and I became pretty much bipolar; so I went off of it- and birth control all together. My mood is back to normal now but it took my period about two months to come back, and then I only got it every two months or so. This time I got my period, and it was for 7 days, went away and came back for 4 or five more and went away again. It's been a month and it keeps coming back. My fiance and I arent currently trying to get pregnant but I'm worried someday in the future I might not be able to because of the depo. Also, I don't know how normal it is to have my period like this. I don't have any insurance and can't go to the doctor. Anyone have any ideas?
